Sung Sot Cave
Situated in the centre of the UNESCO-declared World Heritage area, the Sung Sot or Surprise Grotto is on Bo Hon Island, and is one of the finest and widest grottoes of Ha Long Bay. Ascending to the grotto, the way is covered by trees and foliage, and consists of great paved stone blocks.
Sung Sot Cave is on the same island with Trinh Nu cave. The path to Sung Sot is quite steep and is lined with shady trees. The cave has 2 chambers. The outer chamber is square and is often referred to as the waiting room. The cave’s ceiling is approximately 30 m high. The walls are almost perfectly smooth as if it was built by man. The walls generate a variety of colors that blend with the setting of the area.
After a steep climb of around 50 steps to the mouth of the cave, which is sheltered by natural vegetation, visitors step into another world-one that combines the cool mystery of Sung Sot Cave with soft, diffused light from the outside world.
The first chamber of Sung Sot Cave is known as the waiting room and is around 30 metres high. It is reached by walking down a flight of 10 steps from the mouth of the cave. With walls eroded by Mother Nature and squarish in shape, the waiting room provides a grand entrance to the larger second chamber, which is reached by a 3 metre wide path. It is when they enter the second chamber, that tourists to Sung Sot understand why it is called the Surprise Cave.
The second, or inner chamber, is so large it could hold a thousand people at once. Above and below, stalactites and stalagmites reach to touch each other from floor and ceiling, sometimes meeting in unison. A meandering path around the chamber allows tourists a view of the cave from different angles, and the light from outside, when coupled with the cave’s coloured lighting, creates a magical world, perfect for photographs.
